Application led July 29, 1915.

To @ZZ who/m t muy Concern.'

Be it lrnown that we, @aan Swnernius and "flans T. R. rianirz, a citizenof the United States of America and a subject of the Emperor of Germany,respectively, both residing at N ew Haven, if ew Haven county,Connecticut, have invented a new and useful Firearm, of which thefollowing is a speciiication.

Our invention relates to firearms, and particularly to rifles of thesingle shot variety.

rllhe invention consists in a new and useful cartridge extracting andejecting means which is designed to reliably and effectively dislodgeand eject an empty shell from the chamber of the barrel.

ln the drawings: Figure 1 is a side elevation, partly in section, of themiddle or breech portion of a irearin equipped with our invention. Fig.2 is a similar view showing the parts in a dirlerentjiosition. Fig. 3 isalso a similar view showing the parts in still another position. Fig. 4lis a section on the line 4--4f of Fig. 1. Fig. 5 is a front elevation ofcertain parts detached. Figs. 6, 7 and 8 are perspective views ofdetails.

1 represents the receiver, 2 the' stock, 3 the barrel, e thebreechbloclr, 5 the breechbloclr operating lever, 6 the hammer pivotedto and carried by the breechblock 4, and 7 the trigger, likewise pivotedto and carried by the breech block. rlhe lever 5 is pivoted to theunderside of the receiver frame 1 on the pvot pin 8. 9 is an extensionat the pivoted end of the lever which is connected to the breech blockthrough the medium of a link 10.

l1 is the usual firing pin carried by the breechbloclt for operation bythe hammer 6.

12 is al pin carried by the frame and upon which the rear end of thebreechblock 4e is mounted to slide and partially turn as saidbreechblock is moved up and down. The rear end of the breechbloclr maybe slotted as shown, to receive the pin 12.

13 is a locking shoulder or abutment on the receiver against which ashoulder 14 on the breech block may abut when the breech bloclt islocked up, and the gun is ready for firing, as shown in Fig. 1, in whichposition, said breechbloclr will be solidly held between said abutment,the rear end of the barrel, and the lever pivot 8.

prises an upright arm 15 which is pivotally supported at its lower end,for example on the pinV 8, the upper end of the arm 15 carrying alateral offset 16 which directly engages the rim of the cartridge as itstands in the barrel, so that when the arm 15 is swung back, thecartridge will be extracted and ejected. This extractor is located in arecess or space between the side wall of the breech block and theadjacent side wall of the receiver. At the forward edge of the arm 15,and toward the lower end thereof is a projection 17 which provides twoopposite inclines, as shown, which are designed to cooperate with aspring plunger 18 which is mounted in the front end of the receiver, andis pressed by a spring 19 in a direction to cause the plunger 18 toyieldingly bear against one side or the other of the projection 17. 2Ois a projection at the opposite edge of the arin 15 from the projection17. One edge of this projection 2() is partially beveled, as indicatedat Q1. rlhis projection 2O coacts with another spring plunger 22a-rrnged to project from the side of the breech block it. The projecting endof the spring plunger 22 is likewise partially beveled on that sidewhich faces the incline A 21 on the extractor. 23 is a lug on the sideof the upper part of the breech block 4E which is also designed tocooperate with the eX- tractor in the manner and for the purposedescribed hereafter.

Gperation: Let it be assumed that the V parts stand in the positionshown in Fig. 1, wherein the gun is locked up ready for firing. When thehammer has dropped and the gun has been red, the operator may swing thelever 5 downwardly so as to lower the breech block. When the breechblock has been lowered to a suiiicient extent to clear the empty shellin the chamber of the barrel,-that position being approximatelyindicated in Fig. 2,-the plunger 22 will encounter the end of theprojection 20 on the extractor, so that the further descent of thebreech block will cause the extractor to tilt baclwardly on its pivot 8,thus extracting the'shell. This iirst partial movement of the extracto-ris comparatively slow. llmien, however, the extractor has tiltedsufficiently to cause the point 17 to clear the point 18a of the plunger18, the spring 19 will cause the plunger 18 to jump ahead quickly so asindicated the several views.

to impart a ver f quick backward throw to the extractor, thusguaranteeing the certain ejection ofthe empty shell. rlhe extremerearward movement or position of vthe extractor is indicated in dottedlines, lig` 2. The continued forward swinging movement of the lever 5from the position indicated in Fig. 2 to that indicated in Fig. 3imparts,

in effect, adownward and forward move-V ment to the upper end of thebreech block,

whereby the lng 28 on the latter engagesV cated in 3 to that indicatedin 1,

thus completing a cycle of operations. Y

The efiect of the plunger 18 against the opposite inclines oftheprojection 17 is to hasten the last part of the rearward movement of theextractor for the above purpose, and to also hasten the last'part of theforward movement thereof-so as to guarantee' the seating of the offsetend 16 in Vits inactive position.

Vfhat we claim is:
